Abstract
The invention belongs to the technical field of rice planting fertilizers, in particular to a rice selenium-enriching and cadmium-reducing foliar fertilizer. The foliar fertilizer comprises citric acid monohydrate, small fruit saponin, sodium selenite, urea, potassium chloride, potassium dihydrogen phosphate, soluble trace element compounds, soybean peptides and tartrate. The foliar fertilizer greatly improves the absorption and transformation rate of rice for selenium, and further has a good cadmium inhibiting property, and is rich in nutrients, easily absorbed by the rice, high in selenium enriching and cadmium reducing efficiency and stable in effect after being sprayed to the rice, so that the rice is high in yield.
Description
【Technical field】
The present invention relates to Rice Cropping technical field of fertilizers, and in particular to cadmium foliage fertilizer drops in a kind of Oryza sativa L. selenium-rich.
【Background technology】
Oryza sativa L. is one of the main food in the world, and Chinese more than half population is with rice as staple food.Rice nutrition be worth with
Sanitary quality index, healthy with its people has close relationship.It is reported that, the pollutant of Chinese arable land soil point position are exceeded
Rate is 19.1%, wherein the exceeding standard rate of cadmium is 7.0%.Oryza sativa L. has the habit of enriching heavy metal cadmium, is that absorption cadmium ability is most strong
Large cereal crops.Cadmium is human body non-essential element, to the toxic effect of human body and animals and plants, people's long-term consumption cadmium content
Exceeded food, will face the risk of chronic poisoning.Currently often through soil remediation measure, Cadmium in Soil or effective cadmium are reduced
Content, to reduce rice in cadmium accumulation, this kind of method, often troublesome poeration invests huge；In addition with being arranged by agronomy
